Abstract
A system and method for storing and retrieving file system log information in a cluster computer system is provided. In response to an aborted takeover operation, a surviving storage system stores a set of file replay log information on storage devices associated with the surviving storage system. When the failed storage system re-initializes, it retrieves the file replay log information from the surviving storage system and utilizes the file replay log information to render its disks consistent.
